i owned one for a few years with a few different motors and what not, i used to slide the thing on the street, rain hail or shine, 4wd or 2wd, i used to go along the beach flat out 2nd at 60ish and flick the steering wheel to get it sliding and maintain the speed while fish tailing up and down without a single murmer of a roll.
The drover has way narrower diffs than the wide track suzis. They dont tip at all from my experience. They actually handle really well when you push them with the standard 26inch wheels, have taken some very fast lines through hill runs in mine.
